Can anyone tell me if these 2 hibiscus are the same or is one a tropical and the other not. I rescued them from the dump and would like to care for them properly, one has already bloomed twice (the one on the right). I'm hoping the one on the right is a Hardy Hibiscus and I can plant it outside for the winter (I live in CT). Also, why are the leaves cupping? Thanks for your help.

I'm going to venture a guess and say they're both tropical...

In general, tropical hibiscus leaves are dark green and glossy, and those on hardy hibiscus are medium green and heart-shaped. This isn't always the case, however. The leaves on the hardy species Confederate rose (Hibiscus mutabilis), for example, are large and lobed (not heart-shaped). Those on hardy Swamp rosemallow (Hibiscus grandiflorus) are fuzzy and grayish green and on "Kopper King" reddish. The tropical Mokulei rosemallow (Hibiscus brackenridgei) can have a gray or silverlike leaves.

Hi Val!
I with Ronnie both should be tropical! I tell the difference by sheen. Tropical hibiscus here have so many different leaves as do hardy and rose mallow. Tropical always has a sheen that the others do not. The reason the leaves are cupped could be the plant was exposed to colder temps or a pesticides were sprayed around it. May your week be full of joy!

The one on the right is tropical, the one on the left is probably tropical also.
